(Strip Number 650, Original Publication Date, 9 July 1984)
Panel 1: We find John and Michael at the travel agency so that they can book his flight to Vancouver. He tells the agent that he'd like to buy an airplane ticket for Michael who is traveling alone.
Panel 2: The agent asks if it is a one way or return ticket.
Panel 3: John looks at Mike for a second.
Panel 4: He then makes an asinine and demeaning joke about how he guesses that they might as well have him back. Mike is, of course, alarmed by this.
Summary: Although his intent is clearly to tell Mike that any point in time, he CAN be sent away forever, I can imagine an awkward conversation in which dumb-ass John gets all shirty about how no one can take a joke any longer. John Patterson of Earth....DIE!!!
